The characteristics of the prepared Ag-TiO₂ nanocomposites were identified by Fourier Transform Infra-Red spectroscopy (FTIR), X-Ray Diffraction (XRD), and scanning electron microscopy (SEM) methods. The additives have a significant effect on the particle size distribution and photocatalytic activity of Ag-TiO₂ nanocomposites. SEM images have shown that the particle size distribution of Ag-TiO₂ nanocomposite in the presence of HPC was the best in comparison to the other samples. The photocatalytic activity of the synthesized nanocomposites was investigated for decolorization of methyl orange (MO) in water under UV-irradiation in a batch reactor, and the results showed that the photocatalytic activity of the nanocomposites had been increased by CMC, PEG, PVP, and HPC, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sol-gel%20method" title="sol-gel method">sol-gel method</a>, <a href="https://publications.waset.org/abstracts/search?q=Ag-TiO%E2%82%82" title=" Ag-TiO₂"> Ag-TiO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=decolorization" title=" decolorization"> decolorization</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalyst" title=" photocatalyst"> photocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a> </p> <a href="https://publications.waset.org/abstracts/147280/the-effect-of-additives-on-characterization-and-photocatalytic-activity-of-ag-tio2-nanocomposite-prepared-via-sol-gel-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147280.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> On Performance of Cache Replacement Schemes in NDN-IoT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasool%20Sadeghi">Rasool Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Mahdi%20Faghih%20Imani"> Sayed Mahdi Faghih Imani</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Najafi"> Negar Najafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The inherent features of Named Data Networking (NDN) provides a robust solution for Internet of Thing (IoT). Therefore, NDN-IoT has emerged as a combined architecture which exploits the benefits of NDN for interconnecting of the heterogeneous objects in IoT. In NDN-IoT, caching schemes are a key role to improve the network performance. In this paper, we consider the effectiveness of cache replacement schemes in NDN-IoT scenarios. We investigate the impact of replacement schemes on average delay, average hop count, and average interest retransmission when replacement schemes are Least Frequently Used (LFU), Least Recently Used (LRU), First-In-First-Out (FIFO) and Random. The simulation results demonstrate that LFU and LRU present a stable performance when the cache size changes. Moreover, the network performance improves when the number of consumers increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NDN-IoT" title="NDN-IoT">NDN-IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=cache%20replacement" title=" cache replacement"> cache replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=ndnSIM" title=" ndnSIM"> ndnSIM</a> </p> <a href="https://publications.waset.org/abstracts/84255/on-performance-of-cache-replacement-schemes-in-ndn-iot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84255.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Mosaic Augmentation: Insights and Limitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivia%20A.%20Kjorlien">Olivia A.

For this study, YOLOv4 and YOLOv4 Tiny are trained with and without mosaic augmentation for two sets of objects. While mosaic augmentation improves the performance of simple object detection, it deteriorates the performance of complex object detection, specifically having the largest negative impact on the false positive rate in a complex object detection case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=false%20positives" title=" false positives"> false positives</a>, <a href="https://publications.waset.org/abstracts/search?q=mosaic%20augmentation" title=" mosaic augmentation"> mosaic augmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20detection" title=" object detection"> object detection</a>, <a href="https://publications.waset.org/abstracts/search?q=YOLOV4" title=" YOLOV4"> YOLOV4</a>, <a href="https://publications.waset.org/abstracts/search?q=YOLOV4-Tiny" title=" YOLOV4-Tiny"> YOLOV4-Tiny</a> </p> <a href="https://publications.waset.org/abstracts/162634/mosaic-augmentation-insights-and-limitations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162634.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> 2.5D Face Recognition Using Gabor Discrete Cosine Transform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Cheraghian">Ali Cheraghian</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Hajati"> Farshid Hajati</a>, <a href="https://publications.waset.org/abstracts/search?q=Soheila%20Gheisari"> Soheila Gheisari</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongsheng%20Gao"> Yongsheng Gao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a novel 2.5D face recognition method based on Gabor Discrete Cosine Transform (GDCT).

These rods can be linked together via U-coupling easily. The system is self-stimulated and may cause instabilities due to the inherent behavior of the coupling. In this study, each rod includes an elastic shaft with an angular stiffness and structural damping. Moreover, the mass of shafts is considered via attached solid disks. The impact of the system architecture and shaft mass on the instability of such mechanism are studied. Stability charts are plotted via a method based on Floquet theory. Eventually, the unstable points have been found and analyzed in detail. The results show that stabilizing the driveline is feasible by changing the system characteristics which include shaft mass and architecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coupling" title="coupling">coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20systems" title=" mechanical systems"> mechanical systems</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillations" title=" oscillations"> oscillations</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20shafts" title=" rotating shafts"> rotating shafts</a> </p> <a href="https://publications.waset.org/abstracts/98061/stability-of-a-self-excited-machine-due-to-the-mechanical-coupling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98061.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Optimization of Processing Parameters of Acrylonitrile–Butadiene–Styrene Sheets Integrated by Taguchi Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Sadat%20Miri">Fatemeh Sadat Miri</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Ehsani"> Morteza Ehsani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Farshid%20Hosseini"> Seyed Farshid Hosseini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present research is concerned with the optimization of extrusion parameters of ABS sheets by the Taguchi experimental design method. In this design method, three parameters of % recycling ABS, processing temperature and degassing time on mechanical properties, hardness, HDT, and color matching of ABS sheets were investigated. The variations of this research are the dosage of recycling ABS, processing temperature, and degassing time. According to experimental test data, the highest level of tensile strength and HDT belongs to the sample with 5% recycling ABS, processing temperature of 230°C, and degassing time of 3 hours. Additionally, the minimum level of MFI and color matching belongs to this sample, too. The present results are in good agreement with the Taguchi method.

SGDP encodes micro-pattern features based on local surface higher-order derivative variation. It extracts local information by encoding various distinctive textural relationships contained in a geodesic neighborhood, hence fusing texture and range information of a surface at the data level. Geodesic texture rings are encoded into local patterns for similarity measurement between non-rigid 3D surfaces. The performance of the proposed method is evaluated extensively on the Bosphorus and FRGC v2 face databases. Compared to existing benchmarks, experimental results show the effectiveness and superiority of combining the texture and 3D shape data at the earliest level in recognizing typical deformable faces under expression, illumination, and pose variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20face%20recognition" title="3D face recognition">3D face recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=pose" title=" pose"> pose</a>, <a href="https://publications.waset.org/abstracts/search?q=expression" title=" expression"> expression</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20matching" title=" surface matching"> surface matching</a>, <a href="https://publications.waset.org/abstracts/search?q=texture" title=" texture"> texture</a> </p> <a href="https://publications.waset.org/abstracts/37340/surface-geodesic-derivative-pattern-for-deformable-textured-3d-object-comparison-application-to-expression-and-pose-invariant-3d-face-recognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37340.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> A New OvS Approach in Assembly Line Balancing Problem </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Azimi">P.

This paper examines the balancing effect of a whole production line of a real auto glass manufacturer in three steps. In the first step, processing time of each activity in the workstations is generated according to a practical approach. In the second step, the whole production process is simulated and the bottleneck stations have been identified, and finally in the third step, several improvement scenarios are generated to optimize the system throughput, and the best one is proposed. The main contribution of the current research is the proposed framework which combines two famous approaches including Assembly Line Balancing and Optimization via Simulation technique (OvS). The results show that the proposed framework could be applied in practical environments, easily. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20line%20balancing%20problem" title="assembly line balancing problem">assembly line balancing problem</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20via%20simulation" title=" optimization via simulation"> optimization via simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a> </p> <a href="https://publications.waset.org/abstracts/24107/a-new-ovs-approach-in-assembly-line-balancing-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24107.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">526</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Convective Interactions and Heat Transfer in a Czochralski Melt with a Model Phase Boundary of Two Different Shapes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Faiez">R.

In the present numerical study, the interface shape-effect on the convective interactions in a Czochralski oxide melt is described. It was demonstrated that thermos-capillary flow affects inversely the phase boundaries of distinct shapes. The in homogenity of heat flux and the location of the stagnation point at the crystallization front were investigated. The forced convection effect on the point displacement at the boundary found to be much stronger for the flat plate interface compared to the cone-shaped one with and without the Marangoni flow. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20simulation" title="computer simulation">computer simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20flow" title=" fluid flow"> fluid flow</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20shape" title=" interface shape"> interface shape</a>, <a href="https://publications.waset.org/abstracts/search?q=thermos-capillary%20effect" title=" thermos-capillary effect"> thermos-capillary effect</a> </p> <a href="https://publications.waset.org/abstracts/7920/convective-interactions-and-heat-transfer-in-a-czochralski-melt-with-a-model-phase-boundary-of-two-different-shapes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7920.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Characterization of Inkjet-Printed Carbon Nanotube Electrode Patterns on Cotton Fabric</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Najafi">N.

To prepare the homogeneous SWCNT ink in a size small enough not to block a commercial inkjet printer nozzle, we used a kinetic ball-milling process to disperse the SWCNTs in an aqueous suspension. When a patterned electrode was overlaid by repeated inkjet printings of the ink on various types of fabric, the fabric resistance decreased rapidly following a power law, reaching approximately 760 X/sq, which is the lowest value ever for a dozen printings. The Raman and Fourier transform infrared spectra revealed that the oxidation of the SWCNTs was the source of the doped impurities. This study proved also that the droplet ejection velocity can have an impact on the CNT distribution and consequently on the electrical performances of the ink. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ink-jet%20printing" title="ink-jet printing">ink-jet printing</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title=" carbon nanotube"> carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=fabric%20ink" title=" fabric ink"> fabric ink</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton%20fabric" title=" cotton fabric"> cotton fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=raman%20spectroscopy" title=" raman spectroscopy"> raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=fourier%20transform%20infrared%20spectroscopy" title=" fourier transform infrared spectroscopy"> fourier transform infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=dozen%20printings" title=" dozen printings"> dozen printings</a> </p> <a href="https://publications.waset.org/abstracts/35339/characterization-of-inkjet-printed-carbon-nanotube-electrode-patterns-on-cotton-fabric" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35339.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">422</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Procalcitonin and Other Biomarkers in Sepsis Patients: A Prospective Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neda%20Valizadeh">Neda Valizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Soudabeh%20Shafiee%20Ardestani"> Soudabeh Shafiee Ardestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Arvin%20Najafi"> Arvin Najafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The aim of this study is to evaluate the association of mid-regional pro-atrial natriuretic peptide (MRproANP), procalcitonin (PCT), proendothelin-1 (proET-1) levels with sepsis severity in Emergency ward patients. Materials and Methods: We assessed the predictive value of MRproANP, PCT, copeptin, and proET-1 in early sepsis among patients referring to the emergency ward with a suspected sepsis. Results-132 patients were enrolled in this study. 45 (34%) patients had a final diagnosis of sepsis. A higher percentage of patients with definite sepsis had systemic inflammatory response syndrome (SIRS) criteria at initial visit in comparison with no-sepsis patients (P<0.05) and were admitted to the hospital (P<0.05). PCT levels were higher in sepsis patients [P<0.05]. There was no significant differences for MRproANP or proET-1 in sepsis patients (P=0.47). Conclusion: A combination of SIRS criteria and PCT levels is beneficial for the early sepsis diagnosis in emergency ward patients with a suspicious infection disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergency" title="emergency">emergency</a>, <a href="https://publications.waset.org/abstracts/search?q=prolactin" title=" prolactin"> prolactin</a>, <a href="https://publications.waset.org/abstracts/search?q=sepsis" title=" sepsis"> sepsis</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a> </p> <a href="https://publications.waset.org/abstracts/18189/procalcitonin-and-other-biomarkers-in-sepsis-patients-a-prospective-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Non-Linear Vibration and Stability Analysis of an Axially Moving Beam with Rotating-Prismatic Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Najafi">M.

The link has been rotational and translational motion and it was assumed that the beam is moving with a harmonic velocity about a constant mean velocity. Non-linearity has been introduced by including the non-linear strain to the analysis. Dynamic model is obtained by Euler-Bernoulli beam assumption and modal expansion method. Also, the effects of rotary inertia, axial force, and associated boundary conditions of the dynamic model were analyzed. Since the complex boundary value problem cannot be solved analytically, the multiple scale method is utilized to obtain an approximate solution. Finally, the effects of several conditions on the differences among the behavior of the non-linear term, mean velocity on natural frequencies and the system stability are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-linear%20vibration" title="non-linear vibration">non-linear vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=axially%20moving%20beam" title=" axially moving beam"> axially moving beam</a>, <a href="https://publications.waset.org/abstracts/search?q=bifurcation" title=" bifurcation"> bifurcation</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20scales%20method" title=" multiple scales method"> multiple scales method</a> </p> <a href="https://publications.waset.org/abstracts/67244/non-linear-vibration-and-stability-analysis-of-an-axially-moving-beam-with-rotating-prismatic-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67244.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> miR-200c as a Biomarker for 5-FU Chemosensitivity in Colorectal Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rezvan%20Najafi">Rezvan Najafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Korosh%20Heydari"> Korosh Heydari</a>, <a href="https://publications.waset.org/abstracts/search?q=Massoud%20Saidijam"> Massoud Saidijam </a> </p> <p class="card-text"><strong>Abstract:</strong></p> 5-FU is a chemotherapeutic agent that has been used in colorectal cancer (CRC) treatment. However, it is usually associated with the acquired resistance, which decreases the therapeutic effects of 5-FU. miR-200c is involved in chemotherapeutic drug resistance, but its mechanism is not fully understood. In this study, the effect of inhibition of miR-200c in sensitivity of HCT-116 CRC cells to 5-FU was evaluated. HCT-116 cells were transfected with LNA-anti- miR-200c for 48 h. mRNA expression of miR-200c was evaluated using quantitative real- time PCR. The protein expression of phosphatase and tensin homolog (PTEN) and E-cadherin were analyzed by western blotting. Annexin V and propidium iodide staining assay were applied for <em>apoptosis detection. </em>The caspase-3 activation was evaluated by an enzymatic assay. The results showed LNA-anti-miR-200c inhibited the expression of PTEN and E-cadherin protein, apoptosis and activation of caspase 3 compared with control cells. In conclusion, these results suggest that miR-200c as a prognostic marker can overcome to 5-FU chemoresistance in CRC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colorectal%20cancer" title="colorectal cancer">colorectal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-200c" title=" miR-200c"> miR-200c</a>, <a href="https://publications.waset.org/abstracts/search?q=5-FU%20resistance" title=" 5-FU resistance"> 5-FU resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=E-cadherin" title=" E-cadherin"> E-cadherin</a>, <a href="https://publications.waset.org/abstracts/search?q=PTEN" title=" PTEN"> PTEN</a> </p> <a href="https://publications.waset.org/abstracts/83847/mir-200c-as-a-biomarker-for-5-fu-chemosensitivity-in-colorectal-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83847.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Experimental Investigation on the Effect of Adding CuO Nanoparticles to R-600a Refrigerant on Heat Transfer Enhancement of a Horizontal Flattened Tube</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Akhavan-Behabadi">M.

The effect of different parameters such as mass flux, vapor quality and inside height on heat transfer coefficient was studied. Flattening the tube caused significant enhancement in heat transfer performance so that the maximum augmentation ratio of 163% was obtained in flattened channel with lowest internal height.

The aim of the present study is to use the outcome of several algorithms, which cause decline in IDS errors, in the way that improves system security and prevents additional overload to the system. Finally, regarding the obtained result we can also detect the amount and percentage of more sub attacks.

Nowadays, the market for in-game item purchases and microtransactions or micropayments has been growing increasingly. Since the market should be legal, lawyers and lawmakers around the world have expressed concerns over the legality of online gaming and in-game transactions. The issue is highlighted by the recent emergence of an in-game business model in the name of loot boxes. Similarities between loot boxes gaming and gambling features activities have started a legal debate as to whether loot boxes constitute a form of gambling or whether the game’s use of loot boxes should be considered gambling. Hence, based on the relationship between loot boxes purchasing and problem gambling, the paper investigates the legal effect of the newly emergent phenomenon of loot boxes on online games from the perspective of Iranian law. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serious%20games" title="serious games">serious games</a>, <a href="https://publications.waset.org/abstracts/search?q=loot%20boxes" title=" loot boxes"> loot boxes</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20gambling" title=" online gambling"> online gambling</a>, <a href="https://publications.waset.org/abstracts/search?q=in-game%20purchase" title=" in-game purchase"> in-game purchase</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20items" title=" virtual items"> virtual items</a> </p> <a href="https://publications.waset.org/abstracts/158619/in-game-business-and-the-problem-of-gambling-legal-analysis-of-loot-boxes-from-the-perspective-of-iranian-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158619.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Combining Work and Study: A Solution for Stronger University-Industry Linkage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Payam%20Najafi">Payam Najafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnam%20Ebrahimi"> Behnam Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Montazerolghaem"> Hamid Montazerolghaem</a>, <a href="https://publications.waset.org/abstracts/search?q=Safoura%20Akbari-Alavijeh"> Safoura Akbari-Alavijeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasoul%20Tarkesh%20Esfahani"> Rasoul Tarkesh Esfahani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The combination of work and study has been recently gained lots of attention due to the crucial demand of industries to skillfully trained youth. Nevertheless, the distance between university and industry makes this combination challenging. According to the OECD (2012), in most countries, there is a limited link between students’ field of study and their area of work while studying. On the other hand, high unemployment rates among the specialized workforce, which is common in developing countries, highlights the need to strengthen this relationship. Innovative Center of Isfahan Chamber of Commerce has defined a project called 'POUYESH', which helps students to find related work opportunities to their field of study as well as supporting industries to supply their needed workforce. The present research is sought to explore the effect of the running project as a model of combining work and study on the university-industry linkage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=work%20and%20study" title="work and study">work and study</a>, <a href="https://publications.waset.org/abstracts/search?q=university-industry%20linkage" title=" university-industry linkage"> university-industry linkage</a>, <a href="https://publications.waset.org/abstracts/search?q=POUYESH%20project" title=" POUYESH project"> POUYESH project</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20of%20study" title=" field of study"> field of study</a> </p> <a href="https://publications.waset.org/abstracts/144764/combining-work-and-study-a-solution-for-stronger-university-industry-linkage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144764.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Exploring the Efficacy of Nitroglycerin in Filler-Induced Facial Skin Ischemia: A Narrative ‎Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Feily">Amir Feily</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazhir%20Shahmoradi%20Akram"> Hazhir Shahmoradi Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Ghaedi"> Mojtaba Ghaedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Javdani"> Farshid Javdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Naser%20Hatami"> Naser Hatami</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Kalani"> Navid Kalani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Zarenezhad"> Mohammad Zarenezhad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Filler-induced facial skin ischemia is a potential complication of dermal filler injections that can result in tissue damage and necrosis. Nitroglycerin has been suggested as a treatment option due to its vasodilatory effects, but its efficacy in this context is unclear. Methods: A narrative review was conducted to examine the available evidence on the efficacy of nitroglycerin in filler-induced facial skin ischemia. Relevant studies were identified through a search of electronic databases and manual searching of reference lists. Results: The review found limited evidence supporting the efficacy of nitroglycerin in this context. While there were case reports where the combination of nitroglycerin and hyaluronidase was successful in treating filler-induced facial skin ischemia, there was only one case report where nitroglycerin alone was successful. Furthermore, a rat model did not demonstrate any benefits of nitroglycerin and showed harmful results. Conclusion: The evidence regarding the efficacy of nitroglycerin in filler-induced facial skin ischemia is inconclusive and seems to be against its application. Further research is needed to determine the effectiveness of nitroglycerin alone and in combination with other treatments for this condition. Clinicians should consider limited evidence bases when deciding on treatment options for patients with filler-induced facial skin ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitroglycerin" title="nitroglycerin">nitroglycerin</a>, <a href="https://publications.waset.org/abstracts/search?q=facial" title=" facial"> facial</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20ischemia" title=" skin ischemia"> skin ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=fillers" title=" fillers"> fillers</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20review" title=" narrative review"> narrative review</a> </p> <a href="https://publications.waset.org/abstracts/171621/exploring-the-efficacy-of-nitroglycerin-in-filler-induced-facial-skin-ischemia-a-narrative-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171621.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Prioritization of the Failure Factors of Rural Cooperatives in Iran: The Case of Isfahan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Najafi">Maryam Najafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Rajabi"> Mahdi Rajabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although the rural cooperatives are an effective way for rural development in Iran, their potential is not applied effectively. The investigation of the failures of rural cooperatives helps the authorities to improve the routine procedures and eliminate the current barriers to the success of these cooperatives, and to remove the defects in order to have a more efficient policy. Therefore, this research aims to prioritize the failure factors of rural cooperatives in Isfahan province via the survey research method. For this purpose, the effective factors of these failures were investigated by the available research documents and then by the new information which was obtained from 20 questionnaires from the experts of Central Organization Rural Cooperatives in Isfahan province. The questionnaire results were analyzed by Analytical Hierarchy Process (AHP), Excel, and Expert Choice software. The results of this research showed that the most important failure factor of these cooperatives is the lack of the participation culture of cooperative members and then the performance of Central Organization Rural Cooperatives, and also loss of confidence of the members in the cooperation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooperative" title="cooperative">cooperative</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20cooperatives" title=" rural cooperatives"> rural cooperatives</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20factors" title=" failure factors"> failure factors</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title=" analytical hierarchy process"> analytical hierarchy process</a> </p> <a href="https://publications.waset.org/abstracts/141008/prioritization-of-the-failure-factors-of-rural-cooperatives-in-iran-the-case-of-isfahan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Three-Dimensional Unsteady Natural Convection and Entropy Generation in an Inclined Cubical Trapezoidal Cavity Subjected to Uniformly Heated Bottom Wall</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Fathinia">Farshid Fathinia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical computation of unsteady laminar three-dimensional natural convection and entropy generation in an inclined cubical trapezoidal air-filled cavity is performed for the first time in this work. The vertical right and left sidewalls of the cavity are maintained at constant cold temperatures. The lower wall is subjected to a constant hot temperature, while the upper one is considered insulated. Computations are performed for Rayleigh numbers varied as 103 ≤ Ra ≤ 105, while the trapezoidal cavity inclination angle is varied as 0° ≤ ϕ ≤ 180°. Prandtl number is considered constant at Pr = 0.71. The second law of thermodynamics is applied to obtain thermodynamic losses inside the cavity due to both heat transfer and fluid friction irreversibilities. The variation of local and average Nusselt numbers are presented and discussed.While, streamlines, isotherms and entropy contours are presented in both two and three-dimensional pattern. The results show that when the Rayleigh number increases, the flow patterns are changed especially in three-dimensional results and the flow circulation increases. Also, the inclination angle effect on the total entropy generation becomes insignificant when the Rayleigh number is low.Moreover, when the Rayleigh number increases the average Nusselt number increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transient%20natural%20convection" title="transient natural convection">transient natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=trapezoidal%20cavity" title=" trapezoidal cavity"> trapezoidal cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20flow" title=" three-dimensional flow"> three-dimensional flow</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy%20generation" title=" entropy generation"> entropy generation</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20law" title=" second law "> second law </a> </p> <a href="https://publications.waset.org/abstracts/24831/three-dimensional-unsteady-natural-convection-and-entropy-generation-in-an-inclined-cubical-trapezoidal-cavity-subjected-to-uniformly-heated-bottom-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24831.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> The Effect of β-Cryptoxanthin on Testicular Ischemia-Reperfusion Injury in a Rat Model: Evidence from Testicular Histology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kianoush%20Mohammadnejad">Kianoush Mohammadnejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahim%20Mohammadi"> Rahim Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Soleimanzadeh"> Ali Soleimanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Shalizar%20Jalai"> Ali Shalizar Jalai</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Sareafzadeh%20Rezaei"> Farshid Sareafzadeh Rezaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Testicular torsion and detorsion are significant clinical issues for infertile men. Torsion of the spermatic cord is an emergency condition resulting from the rotation of the testis and epididymis around the axis of the spermatic cord. A rat testis model was used to assess the effects of β-cryptoxanthin on ischemia-reperfusion injury. Twenty healthy male Wistar rats were included and randomized into four investigational groups (n = 5): Group SHAM: In this group, midline incision of the scrotum was performed, and the testicles were taken out for 2 hours with a 720-degree rotation. Group ISCHEMIA: In this group, a midline incision of the scrotum was performed, and the testicles were taken out and underwent ischemia for 2 hours with a 720-degree rotation. Group IS/REP/Oil: In this group, a midline scrotum cut was performed the testicles were taken out, and ischemia was created for 2 hours with a 720-degree rotation and at the end of ischemia 100 µL of corn oil (β-cryptoxanthin solvent) was injected intraperitoneally. Group IS/REP/CRPTXNTN 2.5: The same as group IS/REP/Oil as well as intraperitoneal administration of 100 µL of β-cryptoxanthin (2.5 µg/kg) at the end of ischemia. In all groups, the testes were returned back to the scrotum and, after 60 days, were dissected out and removed for histopathological analyses. β-cryptoxanthin at the dose of 2.5 µg/kg significantly improved histologic indices compared to other treatment groups (p<0.05). β-cryptoxanthin could be helpful in minimizing ischemia-reperfusion injury in testicular tissue exposed to ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-cryptoxanthin" title="beta-cryptoxanthin">beta-cryptoxanthin</a>, <a href="https://publications.waset.org/abstracts/search?q=testis" title=" testis"> testis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ischemia-reperfusion" title=" Ischemia-reperfusion"> Ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Intraperitoneal" title=" Intraperitoneal"> Intraperitoneal</a> </p> <a href="https://publications.waset.org/abstracts/189306/the-effect-of-v-cryptoxanthin-on-testicular-ischemia-reperfusion-injury-in-a-rat-model-evidence-from-testicular-histology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189306.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">18</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Rotor Dynamic Analysis for a Shaft Train by Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Najafi">M.

The basic elements of rotor are the shafts and the disks which are represented as circular cross section flexible beams and rigid body elements, respectively. For more accurate results, the gyroscopic effect and bearing dynamics coefficients and function of rotation are taken into account, and for the influence of shear effect, rotor has been modeled in the form of Timoshenko beam. Lateral critical speeds, critical speed map, damped mode shapes, Campbell diagram, zones of instability, amplitudes, phase angles response due to synchronous forces of excitation and amplification factor are calculated.

The computational fluid dynamic (CFD) models coupled with population balance equation (CFD-PBM) have been extensively employed to investigate the flow behavior in the poly-disperse multiphase fluidized bed reactors (FBRs) utilizing ANSYS Fluent code. In this study, an existing CFD-PBM/ DQMOM coupled modeling framework has been used to highlight its potential to analyze the industrial-scale gas phase polymerization reactor. The predicted results reveal an acceptable agreement with the observed industrial data in terms of pressure drop and bed height. The simulated results also indicate that the higher particle growth rate can be achieved for bigger particles. Hence, the 2D CFD-PBM/DQMOM coupled model can be used as a reliable tool for analyzing and improving the design and operation of the gas phase polymerization FBRs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20balance%20equation" title=" population balance equation"> population balance equation</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed%20polymerization%20reactor" title=" fluidized bed polymerization reactor"> fluidized bed polymerization reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20quadrature%20method%20of%20moments" title=" direct quadrature method of moments"> direct quadrature method of moments</a> </p> <a href="https://publications.waset.org/abstracts/35644/2d-cfd-pbm-coupled-model-of-particle-growth-in-an-industrial-gas-phase-fluidized-bed-polymerization-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35644.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Evaluation of Deformation for Deep Excavations in the Greater Vancouver Area Through Case Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boris%20Kolev">Boris Kolev</a>, <a href="https://publications.waset.org/abstracts/search?q=Matt%20Kokan"> Matt Kokan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Deriszadeh"> Mohammad Deriszadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Bateni"> Farshid Bateni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increasing demand for real estate and the need for efficient land utilization in Greater Vancouver, developers have been increasingly considering the construction of high-rise structures with multiple below-grade parking. The temporary excavations required to allow for the construction of underground levels have recently reached up to 40 meters in depth. One of the challenges with deep excavations is the prediction of wall displacements and ground settlements due to their effect on the integrity of City utilities, infrastructure, and adjacent buildings. A large database of survey monitoring data has been collected for deep excavations in various soil conditions and shoring systems. The majority of the data collected is for tie-back anchors and shotcrete lagging systems. The data were categorized, analyzed and the results were evaluated to find a relationship between the most dominant parameters controlling the displacement, such as depth of excavation, soil properties, and the tie-back anchor loading and arrangement. For a select number of deep excavations, finite element modeling was considered for analyses. The lateral displacements from the simulation results were compared to the recorded survey monitoring data. The study concludes with a discussion and comparison of the available empirical and numerical modeling methodologies for evaluating lateral displacements in deep excavations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20excavations" title="deep excavations">deep excavations</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20displacements" title=" lateral displacements"> lateral displacements</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=shoring%20walls" title=" shoring walls"> shoring walls</a>, <a href="https://publications.waset.org/abstracts/search?q=tieback%20anchors" title=" tieback anchors"> tieback anchors</a> </p> <a href="https://publications.waset.org/abstracts/133141/evaluation-of-deformation-for-deep-excavations-in-the-greater-vancouver-area-through-case-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133141.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Rejuvenation of Premature Ovarian Failure with Stem Cells/IVA Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Vojoudi">Elham Vojoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzieh%20Mehrafza"> Marzieh Mehrafza</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Hosseini"> Ahmad Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Azadeh%20Raofi"> Azadeh Raofi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Najafi"> Maryam Najafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Premature ovarian failure (POF) has become one of the main causes of infertility in women of childbearing age and the incidence of this disorder is increasing year by year. In these patients, poor ovarian response (POR) to gonadotropins reflects a diminished ovarian reserve (DOR) that gives place to few follicles despite aggressive stimulation. Up to now, egg donation is the only way to resolve infertility problems in POF patients. Therefore, some novel aspects such as activating (Akt signaling pathway) and inhibiting (Hippo-signaling) elements have been identified as IVA procedure that promotes primordial follicle activation. In this study, we used the newly developed technique (combination of in vitro activation of dormant follicles (IVA) and stem cell therapy) to promote ovarian follicle growth much more efficiently than the natural, in vivo process for women with POF. Transplantation of Warton Jelly-MSCs to the ovaries of POF patients rescued overall ovarian function. Participants (10 patients) were followed up monthly for a period of six months by hormonal (AMH, FSH, LH and E2), clinical (resuming menstruation), and US (folliculometry) outcomes after a laparoscopic operation. In summary, IVA/WJ-MSC transplantation may provide an effective treatment for POF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=POF" title="POF">POF</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro%20activation" title=" in vitro activation"> in vitro activation</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cell%20therapy" title=" stem cell therapy"> stem cell therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=infertility" title=" infertility"> infertility</a> </p> <a href="https://publications.waset.org/abstracts/149531/rejuvenation-of-premature-ovarian-failure-with-stem-cellsiva-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149531.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Health Trajectory Clustering Using Deep Belief Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Hajati">Farshid Hajati</a>, <a href="https://publications.waset.org/abstracts/search?q=Federico%20Girosi"> Federico Girosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shima%20Ghassempour"> Shima Ghassempour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a Deep Belief Network (DBN) method for clustering health trajectories. Deep Belief Network (DBN) is a deep architecture that consists of a stack of Restricted Boltzmann Machines (RBM). In a deep architecture, each layer learns more complex features than the past layers. The proposed method depends on DBN in clustering without using back propagation learning algorithm. The proposed DBN has a better a performance compared to the deep neural network due the initialization of the connecting weights. We use Contrastive Divergence (CD) method for training the RBMs which increases the performance of the network. The performance of the proposed method is evaluated extensively on the Health and Retirement Study (HRS) database. The University of Michigan Health and Retirement Study (HRS) is a nationally representative longitudinal study that has surveyed more than 27,000 elderly and near-elderly Americans since its inception in 1992. Participants are interviewed every two years and they collect data on physical and mental health, insurance coverage, ﬁnancial status, family support systems, labor market status, and retirement planning. The dataset is publicly available and we use the RAND HRS version L, which is easy to use and cleaned up version of the data. The size of sample data set is 268 and the length of the trajectories is equal to 10. The trajectories do not stop when the patient dies and represent 10 different interviews of live patients. Compared to the state-of-the-art benchmarks, the experimental results show the effectiveness and superiority of the proposed method in clustering health trajectories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20trajectory" title="health trajectory">health trajectory</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering" title=" clustering"> clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=DBN" title=" DBN"> DBN</a> </p> <a href="https://publications.waset.org/abstracts/37834/health-trajectory-clustering-using-deep-belief-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37834.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> An Integrated Framework for Seismic Risk Mitigation Decision Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Sadeghi">Mojtaba Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Baniassadi"> Farshid Baniassadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Kashani"> Hamed Kashani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the challenging issues faced by seismic retrofitting consultants and employers is quick decision-making on the demolition or retrofitting of a structure at the current time or in the future. For this reason, the existing models proposed by researchers have only covered one of the aspects of cost, execution method, and structural vulnerability. Given the effect of each factor on the final decision, it is crucial to devise a new comprehensive model capable of simultaneously covering all the factors. This study attempted to provide an integrated framework that can be utilized to select the most appropriate earthquake risk mitigation solution for buildings. This framework can overcome the limitations of current models by taking into account several factors such as cost, execution method, risk-taking and structural failure. In the newly proposed model, the database and essential information about retrofitting projects are developed based on the historical data on a retrofit project. In the next phase, an analysis is conducted in order to assess the vulnerability of the building under study. Then, artificial neural networks technique is employed to calculate the cost of retrofitting. While calculating the current price of the structure, an economic analysis is conducted to compare demolition versus retrofitting costs. At the next stage, the optimal method is identified. Finally, the implementation of the framework was demonstrated by collecting data concerning 155 previous projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title="decision making">decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=demolition" title=" demolition"> demolition</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20management" title=" construction management"> construction management</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20retrofit" title=" seismic retrofit"> seismic retrofit</a> </p> <a href="https://publications.waset.org/abstracts/56270/an-integrated-framework-for-seismic-risk-mitigation-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56270.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Waste-Based Surface Modification to Enhance Corrosion Resistance of Aluminium Bronze Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wilson%20Handoko">Wilson Handoko</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Pahlevani"> Farshid Pahlevani</a>, <a href="https://publications.waset.org/abstracts/search?q=Isha%20Singla"> Isha Singla</a>, <a href="https://publications.waset.org/abstracts/search?q=Himanish%20Kumar"> Himanish Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Veena%20Sahajwalla"> Veena Sahajwalla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aluminium bronze alloys are well known for their superior abrasion, tensile strength and non-magnetic properties, due to the co-presence of iron (Fe) and aluminium (Al) as alloying elements and have been commonly used in many industrial applications. However, continuous exposure to the marine environment will accelerate the risk of a tendency to Al bronze alloys parts failures. Although a higher level of corrosion resistance properties can be achieved by modifying its elemental composition, it will come at a price through the complex manufacturing process and increases the risk of reducing the ductility of Al bronze alloy. In this research, the use of ironmaking slag and waste plastic as the input source for surface modification of Al bronze alloy was implemented. Microstructural analysis conducted using polarised light microscopy and scanning electron microscopy (SEM) that is equipped with energy dispersive spectroscopy (EDS). An electrochemical corrosion test was carried out through Tafel polarisation method and calculation of protection efficiency against the base-material was determined. Results have indicated that uniform modified surface which is as the result of selective diffusion process, has enhanced corrosion resistance properties up to 12.67%. This approach has opened a new opportunity to access various industrial utilisations in commercial scale through minimising the dependency on natural resources by transforming waste sources into the protective coating in environmentally friendly and cost-effective ways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20bronze"
